Zamenis flagellum piceus Cope. 



Bascaniuni piceum Cope, I. c, 6'25 ; Z. flarjeUiformis (part) BouL, I. c,

 Am. Fauna, No. 7, 209. 



The type specimen, from Camp Grant, Arizona, has 19 rows of 

 scales; 17 is probably the usual number, as Mr. Stejueger mentions 

 one with that number, which agrees with a living example received 

 at the Zoological Gardens in 1894 from Tucson; this speci- 

 men had 8 upper labials on one side and 9 on the other. The 

 color in life was a rich dark brown wiih a purplish tinge, poste- 

 riorly most of the scales were light brown at the base; the belly was 

 pink slightly spotted with dusky, Avhich increased anteriorly until 

 the throat was nearly black ; there was a little pink on the pre- 

 oculars and lower labials; rest of head very dark. The pink 

 rapidly faded to yellow in alcohol. This specimen is now in the 

 Academy's collection. Ventrals 196; subcaudals 108; length 

 1,650 mm. (tail 380), Cope's specimen measured 1,263 mm, and 

 the tail was proportionately longer (355 mm), 



Hab.— The three specimens known ai-e from southern Arizona.
